HO-Scale Intermountain SD40-2 prior to TCS WOW121-Diesel Decoder, IB-MB2, and INT-SH3 WOWSpeaker Kit installation.
To start off this install, we must first remove the front coupler its housing on the A-unit only. Once that is complete, the shell will lift off of the chassis.
Do this by holding the fuel tank with one hand and lifting the shell off by pressing up underneath the end platforms with your other hand.
Removing the shell on the B-unit is done the same way as the A-unit however, the coupler does not need to be removed.
With the shell off, we can now remove the factory light board. First disconnect the wire harnesses from the board.
Once the wire harnesses are loose, the factory light board can easily be unscrewed from the motor mount.
Make sure to hold onto the four screws as they will be used to secure the IB-MB2 back in place.
Next, remove the stock speaker and its housing. This, along with its screws will not be used.
Now with the factory light board removed, we can now mount and secure the IB-MB2 with the four screws removed earlier.
We can also screw down the INT-SH3 speaker housing kit.
Before screwing down the INT-SH3, make sure to solder the original speaker harness onto the new 28mm WOWSpeaker that came in the kit.
Additionally, some CA glue works great to keep it in place during the installation.
With all three main components mounted, we can now close up the locomotive and reinstall the coupler assemblies.
Be sure to be mind full of wire routing and reassembly of the shell as to not damage or foul the installation.
You have now installed a TCS WOW121-Diesel Decoder, IB-MB2, and INT-SH3 WOWSpeaker Kit into your HO-Scale Intermountain A/B FT locomotive set.
